This weekend, celebrate Earth, have a movie day and check out some super cool planes at the Udvar-Hazy Center

Do roasted green chiles and live music sound appealing to you? What about hands-on workshops and engaging discussions about sustainability and farmers market fresh veggies? This weekend, look no further than the National Museum of the American Indian’s annual, three-day long Living Earth Festival. The event celebrates indigenous contributions to environment and encourages the diffusion of knowledge and activism. The chiles, roasted by Cherokee, Siletz and other tribal farmers, growers and chefs, are just a small part of the festivities. Tribal-owned food cooperatives will discuss sustainability while local and Native chefs compete in an Iron Chef-style cook-off. Hands-on family activities will also be offered. The festival includes a live outdoor concert featuring the talents of Wes Studi, Stevie Salas, Jack Gladstone, Kinnie Starr, and Brule. Free. 10:30 a.m. to 4:30 p.m. through Sunday July 22.

The heat has been unbearable this summer, so why not escape it with a good movie? As part of the Dance DC Festival, the American Art Museum is offering two viewing options depending on your mood. If you’re looking for a thriller, Black Swan, starring tutu-costumed Natalie Portman, will show at 1:00 p.m. For those of you feeling a little nostalgic for bell bottoms, disco balls and a younger, (more fit) John Travolta, Saturday Night Fever will show at 4:00 p.m. Free. McEvoy Auditorium, American Art Museum.

Sand strikers, also known as bobbit worms, are primitive-looking creatures that lack eyes, or even a brain. Despite this, they are savage predators who shoot out grapple-like hooks to reel in passing fish.
